The answer is regularly updating firmware on networking equipment, along with implementing redundant power and VLANs, as the three best practices for network expansion. Firmware updates patch security vulnerabilities and improve device stability, which is critical when scaling a network to handle more traffic and devices. Redundant power supplies ensure uptime by keeping switches and routers running if one power source fails, directly supporting growth through fault tolerance. VLANs logically segment traffic to reduce congestion and enhance security, making them essential for expanding businesses. On the CompTIA ITF+ FC0-U61 exam, this question tests your understanding of foundational network maintenance and scalability concepts, often appearing in scenario-based multiple-choice questions. A common trap is choosing only hardware upgrades like faster cables, while neglecting the ongoing management tasks. Remember the mnemonic “Firmware, Power, VLAN” as the three pillars of expansion—think of them as the “F-P-V” foundation for growth.
FC0-U61 Infrastructure Practice Question
This FC0-U61 practice question tests your understanding of infrastructure. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A small business is expanding and needs to ensure their network infrastructure supports growth. Which THREE practices should they implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy redundant power supplies for critical devices
Redundant power supplies ensure that critical network devices like switches and routers remain operational even if one power supply fails, minimizing downtime during business expansion. This practice directly supports network availability and growth by providing fault tolerance for essential infrastructure components.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Deploy redundant power supplies for critical devices
Why this is correct
Redundant power supplies increase uptime and reliability.

✓
Implement network segmentation using VLANs
Why this is correct
VLANs improve performance and security by separating traffic.

✗
Use a single subnet for simplicity
Why it's wrong here
A single subnet can become congested and insecure as the network grows.
✓
Regularly update firmware on networking equipment
Why this is correct
Firmware updates fix vulnerabilities and improve performance.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use static IP addressing for all devices
Why it's wrong here
Static IPs are not scalable for a growing network; DHCP is preferred.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may choose 'Use a single subnet for simplicity' thinking it reduces complexity, but it actually hinders scalability and introduces broadcast domain issues that degrade performance in a growing network.
Detailed technical explanation
How to think about this question
Network segmentation via VLANs (IEEE 802.1Q) logically separates broadcast domains, reducing unnecessary traffic and improving security by isolating sensitive data traffic. Regular firmware updates patch vulnerabilities and bugs in protocols like STP (802.1D) or OSPF, ensuring stability and compatibility with new hardware as the network scales.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
